Redknapp told Bet Victor: "Another week, another Alexander Isak star man, what a player this guy is!
"I'm not sure if there's a better player in the country right now, he just looks like he'll score a couple in every game, particularly at home. Newcastle have been very good going forward all season, Eddie Howe will be frustrated with the amount of injuries at the back, that's what's really cost this side this season.
"Anthony Gordon is another lad who seems to always be in this team, but how can I leave him out? He was fantastic in that second half against Sheffield United. He won a penalty, created a couple of the goals and was just causing so many problems for Sheffield. Right now, he's probably one of Gareth Southgate's form players and I just can't see how he won't be on that plane to Germany."
